Proof Research PXT Tikka T3X Carbon Fiber Prefit Barrel 308 Winchester 24" Sendero Contour 1:10" Twist

Overview

The Proof Research PXT carbon fiber prefit barrel for the Tikka T3X is chambered in .308 Winchester with a 24-inch length, Sendero contour, and 1:10-inch twist rate. It utilizes PXT (Proof Exponential Twist) rifling technology, which is engineered to reduce engraving force and throat erosion for smoother projectile engagement. This technology helps improve consistency, reduce felt torque, and extend barrel life. The barrel is wrapped in high-strength, aerospace-grade carbon fiber with a proprietary matrix resin, offering extreme temperature resistance and efficient heat dissipation. It is up to 64% lighter than traditional steel barrels of a similar contour. Each barrel arrives threaded and chambered, ready to shoulder directly to the action without additional machining.
